You're the living embodiment of that norm mcdonald joke. I really don't understand this mentality at all. It's like you've been brainwashed.
Pretty sure that it's the people murdering and terrorising people on trains and other public places who are terrible for social/cultural cohesion, and not the fact that people are aware of who is doing this. But yes, let's bring 1984 to life and have the government gaslight people and lie about what they can see with their own eyes, that will be great and definitely not result in any social unrest.
